King
Wen (Ji family in 1076 BC) founded the Zhou dynasty after the Shang dynasty.
The dynasty is known for its social hierarchy, language, length of reign and
military leaders. Iron Age encouraged the dynasty’s government in
centralization. Through it, the iron tools substituted the wood ones to make
the agriculture labor faster and more productive. The military also benefitted
from the swords and iron armors. Because of this, states also had confidence
into fighting each other, provided by the new tools. This induced more wars
against states and called “The Period of the Warring States”.
